Dual-Bus Mode Configurations

For a dual-bus mode configuration, the SCSI Bus Split switches on the switch card of a 2104 Model DU3 must be set to On.

Each 2104 Model DU3 in the configuration is connected either to one external SCSI connector on an adapter card, or to an integrated SCSI port. If an adapter card has four external SCSI connectors, it can be connected to up to four 2104s (Model DU3).

The external SCSI connectors can be either on the same adapter card, or on two separate adapter cards. If the connectors are on two separate adapter cards, these adapter cards can be either both be in the same using system or be in two separate using systems.
